Types of paints for concrete

Concrete paints are used to coat ceilings, floors, paving slabs, walls, and foundations. Certain paints and varnishes are intended exclusively for outdoor use, while others are meant only for interior use. Their performance characteristics and properties differ from one another.

Exterior paints must possess specific qualities such as high moisture resistance, frost resistance, wear resistance, vapor impermeability, beautiful appearance, and quick drying times because buildings and structures are subjected to a variety of external factors.

The most crucial requirement for interior design materials is their safety for the environment and their non-harmful effects on human health. Interior enamels also need to be resistant to different mechanical forces and liquid penetration.

Classification of concrete paints by composition

• Acrylic paints. Most often, unpainted concrete surfaces are treated with acrylic paint for concrete. It contains acrylic resins and polymer particles. The ratio of the components determines how matte or glossy the result will be. Acrylic is harmless to health, is water-resistant, and is easy to apply. There is a huge variety of acrylic paint colors. Acrylic-silicone enamels contain silicone additives – polymer components that contain silicon particles. The introduction of additives allows you to give the paint elasticity. The consumption of acrylic paint on concrete usually varies within 170-200 g / m 2 .

• Epoxy paints. Two components of epoxy paint for concrete, you need to mix with a construction mixer. After covering the painted surface with a layer of paint, it forms a protective film on the concrete. Epoxy paints protect concrete well from moisture, and their color is always rich and bright. Their main disadvantage is a small variety of colors. Consumption: 300-350 ml / m 2 .

• Vinyl paints. Vinyl enamel is used in external and internal work. It has a rich color, the average service life is seven years. Even the initial layer of vinyl paint is enough, so you can refuse to apply a second layer. The enamel has virtually no odor, its drying time is 2 hours.
• Polyurethane paint for concrete. Usually polyurethane enamel is used to cover concrete floors. It resists aggressive environments well, and also resists mechanical destructive factors. The main disadvantage of polyurethane-based compositions is a long drying time. It is 2-14 days. Consumption: 160-200 g / m 2 .

• Water-based paints. Such paint compositions are resistant to high temperatures. They are environmentally friendly. The surface after coating with paint will be waterproof and frost-resistant. Consumption: 550 and 350 g / m 2 for the first and subsequent layers, respectively.

• Rubber paints. They are made from a water-dispersed solution, a pigment additive and acrylates. The paint composition creates an impermeable polymer film on the concrete surface. The drying time of the paint is 20 minutes, and the painting itself can be done even at subzero temperatures. Rubber paint is often used in unheated rooms. Consumption: from 400 g / m2 (for 2 layers).

Paints for concrete by type of surface to be painted

• Facade paint for concrete. The outer part of the building is coated to protect the surface from water, precipitation, dirt, fungi and dust. Enamel for facade treatment must have high penetrating ability, as well as other properties of compositions for outdoor work.
• Paint for concrete for the floor. To paint the floor, you will need paint that has high wear resistance, durability and moisture resistance. What is the best way to paint a concrete floor in a cold garage? In order to achieve the desired result, only special paints should be used. For example, acrylic, polyurethane paints, epoxy varnishes and enamels or liquid glass can be used.
• Paint for the foundation. Here"s what you can use to paint a concrete foundation: acrylic, alkyd, polyurethane, silicone and epoxy enamels. The choice of paints depends on the material being painted and the factors affecting it. For example, for regions with a cold climate, epoxy compounds should be chosen, for coating porous concrete – silicone.
• Paint for paving slabs. How to paint concrete paving slabs? To paint the tiles, you need to use paints with high wear resistance and water resistance. Rubber, polyurethane and alkyd paints are used to paint the tiles.
• Paint for concrete for blind areas. The blind area must be protected from precipitation, make its surface more wear-resistant and durable. How to paint a concrete blind area? It is best to use polymer or epoxy paints and polyurethane enamel.
• How to paint a concrete garden path? The requirements for paint for a garden path in this case are the same as for enamel for paving stones or paving slabs. Polyurethane varnishes, acrylic and epoxy paints for concrete intended for outdoor use, and rubber enamel can be used for painting.

Methods of painting concrete surfaces

Concrete surface painting can be done using two essentially different technologies: deep painting and surface painting. Chemical reactions take place during deep painting, causing the paint to literally eat into the concrete and produce a very durable color. Surface painting is most commonly used because it is much less expensive. The paint’s quality determines the coating’s strength and longevity.

The paint composition can be sprayed, brushed, or roller applied to concrete. Prior to painting, the surface ought to be thoroughly cleaned and, if required, primed. Periodically, the color coating must be changed.

Manufacturers of paints for concrete

The primary distinction among paints is their chemical makeup. It is the foundation for all of the paint coating’s properties. There’s a huge assortment of paints available right now, in every shade and texture.

Conclusion

Concrete paint will shield the surface from mold, dust, moisture, and dirt. The concrete has a nice appearance thanks to the coating, and it will last for a long time without losing its strength or structure. The kind of surface to be painted, its intended use, and the operating environment all influence the paint selection.

Concrete surfaces can be painted to greatly improve both their durability and appearance. Selecting the appropriate paint type is essential to getting the best results. Paints such as epoxy, acrylic, and polyurethane are excellent choices, each with special advantages for various applications and conditions.

It’s critical to correctly prepare the concrete surface before painting. To get rid of any grease, dirt, or old coatings, give it a thorough cleaning. Fix any damage or cracks to guarantee a uniform, smooth finish. A primer application can improve paint adhesion and extend its lifespan.
